WILLIAM I-I. KELLY AND ALFRED TSCHINKEL, OF NEIV YORK, N. Y.

ELECTROMAGNETIC WATER-M ETER.

SPECIFICATION forming part of Letters Patent No. 697,492, dated April 15, 1902. Application filed March 15, 1901l Serial No. 51,313. (No model.)

To tI/Z whom t may concern:

Be it known that we, WILLIAM H. KELLY IVe will now proceed to describe the elecl tromagnetic water-measuring device, pointing out afterward the novelty of same in a claim.

In the accompanying drawings, Figure 1 is a sectional front elevation of a Water-meter and an electromagnetic counting apparatus, both connected in the same circuit. Fig. 2is a front elevation of the counting apparatus. Fig. 3 is a sectional side elevation of same. Figs. 4 and 5 is a front respective side elevation of a rotary cylinder bearing the electriccircuit-closing brush.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, G is a rotary cylinder. Its outer face is provided with partial straight and partial spiral rods or grooves G2. Its ends G Gs are conical extending, of which G' is bearing a rotary spindle B, having its free end tted to a conical bore located on a cross-bar M, which is secured to the inner face of a cylindrical tank L we will later describe. Said conical end G is provided with a circuit-closing brush I, engaging with a pair of electroconducting buttons I I', insulated and secured to inner face of a cylindrical tankL at every revolution the rotary cylinder G will make. Said tank L is serving as an incasing for the rotary cylinder G. A sharp-pointed rod or axis H extends from the side G and is iitted to a small opening H', located in the cross-bar M. The electric buttons I I and the electromagnetic counting apparatus are connected in the same circuit. Said counting apparatus, as shown in Figs. l, 2, and 3, consists of a base-plate, an electromagnetic coil B mounted thereon, its armature-lever C having one end journaled to the guide-rod of a ratchet-wheel Z, operated by the tooth D, journaled to the armature-lever C. Said operating-tooth D has its movement controlled by a retainingspring S. The counting mechanism consists of a series of cog-wheels Z Z2 ZS and onetooth cogs X' X2 X3, hands, and dials.

To show the operation of our new device, we let the water enter into the tank L, where (shown by an arrow in Fig. l) the circulating Water will set the cylinder G in rotary motion by thus closing and opening the electric circuit at each rotation, energizing an electromagnetic coil, its armature-lever actuating a ratchet-wheel and the connected counting mechanism.

Having thus described our invention, We claim as new and desire to secure by Letters Patent- In combination, a water-supply pipe provided with an enlarged portion or casing, cross-bars mounted therein at the ends of the casing, a rotary cylinder provided with pointed axes mounted in said enlarged portion or casing, said axes being mounted in the crossbars, a series of curved grooves upon the surface of the cylinder, conical ends to said cylinder, a switch carried by the cylinder, and electrical connections adapted to be operated every revolution of the cylinder to measure the iiow of water through the pipe.
